by Renee Maltezou and George Hatzidakis, Reuters, Greece - Greece's first gay weddings were held on Tuesday when two couples, abetted by a sympathetic local mayor, defied the threat of criminal charges and the wrath of the Orthodox church to tie the knot on a tiny Aegean island. One gay and one lesbian couple took advantage of the failure of Greek civil law to specify gender in matrimony and took vows at municipal offices on the southeast Aegean island of Tilos.
